My present invention relates to an imshuttle may be employed if desired. Because, provement in looms. however, the material being worked upon is The manufacture of woven material from relatively expensive, I prefer to utilize the filaments that are of round, or relatively power driven shuttle. round, cross-sectional area is comparatively The object of my invention, therefore, is 65 easy in that no attention need be paid to the an improved loom for weaving tapelike filaposition which such filaments may lay as they ments. are brought into association with the warp In the accompanying drawings illustrating filaments by the shuttle.

The usual hand loom method of Flg. 13 lsavlew of one of the heddle wires. manufacture is extremely slow and, there- Referrlng to the drawings, 10 and 11 are fore, relatively expensive and no loom of side frame members spaced apart from each which I am aware is capable of rapidly weavother at the bottom by a transverse member ing such basket weave material. The mate- 12 and by a shaft 13. Formed integral with rial utilized is leather, real or artificial, in the side frame members 10 and 11 at the upper narrow strips and with the warp filaments ends thereof and extending outwardly and ofone color and the woof filaments of anupwardly therefrom are arms 14 and 15. other color. The arms 1 1 are parallel to each other, as are In carrying out my present invention I also the arms 15, and connecting and spacing have devised an improved form of loom in the arms 14 is a rod or shaft 16, while conwhich the woof filaments are delivered to the necting and spacing the arms 15 is a shaft or warp filaments by a shuttle that is preferrod 17. Each of the side frame members 10 ably power driven, and in which shuttle is and 11 has formed integral therewith a brace 4 provided means for delivering the tapelike 18 and in these braces are formed aligned filament to the warp filaments with the debearings 19 and in such aligned bearings is sired side uppermost. In the preferred form rotatably mounted a shaft 20. of my invention the shuttle is power driven, Formed in the side frame members 10 and although such is not necessary, though de- 11 are aligned bearings 21 and in such aligned sirable, and a freely running or thrown bearings is rotatably mounted a drive shaft 22. Secured to the drivingshaft 22 is pul ley 23 of any suitable diameter and over which runs a belt 24, leading to any suitable source of power and by means of which the drive shaft 22 rotated. Secured to one end of the shaft 22 is a pinion 25 which meshes with and drives a gear 26 secured to one end of the shaft 20 and in operation the shaft 20 rotates in the direction of the arrow shown in Fig. 7. Secured to the upper face of each of the side frame members 10 and 11 by bolts 27 and parallelly arranged with respect to each other are frames 28. These frames 28 are tied together by an integrally formed crossbar 29 that extends across the space between the frame members 10 and 11. At the upper end of each ofthe frame members 28 and extending outwardly from one face thereof are two shafts 30, and rotatably mounted on each of such shafts are guide oulleys 31. The guide pulleys of the same diameter and the lower portions thereof lie in the same'horizontal plane, as will be obvious from an inspection of 4 to 6. Also mounted in each of the frames 28 and extending outwardly from one face thereof is a shaft 32, and on each such shaft 32 is rotatably mounted a guide pulley 33. The upper portion of each of the guide pulleys 33 lies in the same horizontal plane and, therefore, the pulleys 32 are spaced below and parallel to the guide pulleys'3l; The guide pulleys 31 and 33 constitute a shuttle race.

34 designates a rectangular member provided on its upper edge with a groove 35 adapted to engage with the guide pulleys 31 and on its lower face with a groove 36 adapted to engage with the guide pulleys 33. The member 34 constitutes the body member of a shuttle and it will be obvious that such shuttle may be reciprocated across the gap between the side frame members 10 and 11 or from the position shown in Fig. 6 through the position shown in Fig. 4 and into a position shown to the extreme left of Fig. 6. In the end groove in the shuttle member 34 is positioned a rack 37. In each of the frame members 28 is rota-tably mounted a shaft 38, such shaft being parallel to the shafts 30 and 32. Secured to one end of each of such shafts is agear 39, these gears being equal in pitch and diameter and the teeth of these gears being adapted to engage with the teeth of the rack 37 in the under groove of the shuttle member 34. Formed in the cross bar 29 is groove in which is slidably mounted a rack 40, such rack sliding transversely of the gap between the side frame members 10 and 11 and parallel to the direction of travel of the shuttle member 34. Secured to the ends the shafts 38 remote from the gears 39 are pinions 41, which pinions are in engagement with the rack 40. It will be obvious, therefore, from the abovedescription that the gears 39 rotate in the same direction and at the same speed,

to the ri ht the direction of rotation of such gears being controlled by the direction of movement of the rack 40. Also it will be obvious that the direction of reciprocation of the shuttle member 34 is also controlled bythe direction of reciprocation of the rack 40. Secured to the shaft 20 at substantially the central portion thereof is a cam member 42 in which is formed a cam race 43.

Secured to the crossbar12 by bol 44 is a stub shaft 45 and to the stub shaft is pivo ally attached the lower end of a lever 4 Intermediate the ends of he lever 46 is rotatably mounted a camroller 47 which works in the cam race 43. To the upper nd of the ever 46 is pivotally attached one end of a connecting rod 48, the other end of this connecting rod being pivotally attached to the rack at the point 49. It will be obvious from the above description that as the shaft 20 is rotated from power delivered by the belt 24 that an oscillating movement will be imparted to the upper end of the lever 46 and a reciprocating movement imparted to the rack 40 and, therefore, a reciprocating movement imparted to the shuttle member 34.

Referring to F ig. 4 and assuming theiipper end of the lever 43to be moved tow; d the left, then obviously a corresponding movement LO the left will be imparted to the rack 40 by the connecting rod 48 and under these circumstances the gears 39 will be rotated in the direction of the arrow shown in such figure, nd, therefore, the shuttle 34 will be moved to the right. As the movement of the shuttle member 34 continues to the right the rack 37 in the under groove thereof will move out of mesh with the left hand gear 39 but the movement of such shuttle member 34 will continue until it reaches the extreme right hand position or the position shown in Fig. 6.

At this time also the lever 46 has moved to its extreme left handposition and further rotary movement of the shaft 20 will cause a movement of the upper end of the lever 46 r with a corresponding movement to the left, as viewed in Fig. 3, or the shuttle member 34. This movement of the shuttle member 34 to the left will continue and when the shuttle member 34 has moved enough it will engage with the left hand ar 39 and, therefore, the left hanc, movement of the shuttle member 34 will continue until the upper end of the lever 46 has attained its extreme right hand position, as viewed in Fig. 6, even though during this movement the rack 37 in the shuttle member 34 moves out of engagement with the right hand gear 39. This mechanism, therefore, provides ferreciprocating the shuttle member 34 across the gap between the side frame members 10 and 11, leaving at the ends of the stroke of the shuttle member 34 the space between such side frame members 10 and 11 clear.

Secured to each of the frame members 28 are parallelly arranged vertically disposed pairs of rods 50, each pair of rods passing through plates 51 secured to the upper face of the side frame members 10 and 11 by the bolts 27. Corresponding rods on the frame members 28 on each side of the gap between the side frame members 10 and 11 are parallel to each other, as well as being in alignment, and slidably mounted on the pairs of rods 50 are heddles 52 and 58 respectively. Each of the heddles 52 and 53 are provided with. the necessary group of heddle wires 54, is usual.

Extending downwardly from and at each side of the heddle 52 are members 55 and in each of such members 55 is rotatably mounted a roller 56. Secured to the shaft 29 ad jacent the bearings 19 by set screws 57 are cams 58. The heddle 52 rests on the cams 58 and holds the rollers 56 in engagement with such cams by the weight of the heddle and rotation of the shaft 20 causes, through the cams 58, a vertical reciprocatory motion of the heddle 52. At each side of the heddle 53 is a downwardly extending member 59 and on each of these downwardly extending members is rotatably mounted a roller 60. Secured to the shaft 20 by set screws 61 are cams 62 similar to but oppositely disposed with respect to the cams 58. The heddle 53 also maintains the rollers in engagement with the cams 62 by the weight of such heddles and the cams 62, on rotation of the shaft 20, causes a vertical reciprocatory motion of the hed-dle 53. The reciprocatory motion is imparted to the heddles 52 and 53 simultaneously and the cams 58 and 62 are so formed as to maintain such heddles at rest for a predetermined portion of the rotation of the shaft 20, as will be obvious from an inspection of Fig. 7, for example.

At the upper end of the aligned upwardly extending arms 14: are formed bearings 65, in which bearings is rotatably mounted a shaft 66, and in this shaft is arranged an elongated roll 67, preferably of resilient mate ial. Securec to and extending between the arms 1 f, below the shaft 65, is a shaft 68 and at each end of such shaft is rotatably mounted a link 69. These links have bearings formed the rain that are in alignment with each other, and rotatably mounted in such bearings is a shaft 70.

Secured to the shaft 70 is a roller 71, preferably of resilient material, and also preferably the rollers 67 and 71 are of the same diameter, although this is not essential. On each of the links 69 is formed an integral extension 72 threaded to receive the lower threaded end of adjusting bolts 7 8. Formed integral with the bearings 65 are extensions 74 drilled to allow free passage therethrough of the bolts 7 3. By manipulating the bolts 73 the degree of tension existing between the rollers 67 and 71 may be regulated, as desired. Adjacent one end of the shaft 66 is secured a gear 75 that meshes with a. gear 76 of like diameter and pitch that is secured to one end of the shaft 70. These gears 75 and 76 insure that the rollers 67 and 71 rotat-e in opposite directions and at the same rate of speed. Secured to the bearings 71 by bolts 77 are plates 78, and secured to such plates 76 is a member 7 9, which lies, as will be obvious from an inspection of Fig. 1, to one side of the rolls 67 and 71. This member 79 is provided with a plurality of perforations 80 through which may pass and be guided the material constituting the warp elements of the material to be woven. This perforated member 79, therefore, acts as a guide for such material. Secured to the shaft 66 adjacent the gear 75 is a ratchet 81,

and rotatably mounted on the shaft 66v adj acent the ratchet 81 is a lever 82. Pivotally mounted on the lever 82 is a pawl 88 kept in engagement with the teeth of the ratchet 82 by spring 84 as the lever 82 is oscillated about the shaft 66 as a pivot and intermittent rotary movement is imparted to the shaft 66 by the pawl 83 and ratchet 81.

At the upper ends of the arms 15 are formed aligned hearings, in which is rotatably mounted a shaft 85, and on this shaft is secured a roll 86 preferably of resilient material, and also preferably of the same diameter as the rolls 67 and 71. Extending between the arms 15 below the shaft is a shaft 87 and on the ends of this shaft are rotatably mounted links 88. At the outer end of the links 88 are formed hearings in which is rotatably mounted a shaft 89 and on such shaft is secured a roller 90 preferably of resilient material and of the same diameter as the roll 86. Formed integral with the links 88 are lugs 91 threaded to receive the lower threaded end of adjusting bolts 92 that pass through perforations in integrally formed members 93 on the upper ends of the arms 15. By means of the threaded bolts 92 the tension between the rolls 86 and 90 may be regulated. Secured to the shaft 85 is a gear 9% which meshes with and drives a similar gear 95 secured to the shaft 89 and, therefore, insures rotation of the shafts 85 and 89 in opposite directions and at the same rate of speed. Secured to the shaft 85 adjacent one end thereof is a ratchet 96. Pivotally mounted on the shaft 85 adjacent the shaft 96 is a lever 97 carrying a ratchet 98 that is constantly reptin engagement with the ratchet 96 by spring 99. Oscillation of the lever 97 insures a rotation of the shaft 85 in the direction of the arrow shown for example in Fig. 7. Pivotally attached to the lower ends of the levers 82 and 97 is a connecting rod 109 which insures that the levers 82 and 97 oscillate in unison and, therefore, insure that the pairs of rollers 67, 71, 86, rotate in unison and at the same rate of speed.

The tapelike filaments 101 constituting the warp filaments of the material to be woven pass through the perforations 80 in the guide 79, thence through the space between the rollers 67 and 71, thence through the holes in the heddle wires 54 in the heddles 52 and 53, as is usual, and thence through the space between the rollers 86 and 90. The tension on the warp filaments 101 may be any desired, such tension being adjusted in the usual and normal way. I

Pivotally mounted on the shaft 13 and extending upwardly therefrom is a frame 102 having formed at its upper end arectangular portion 103 carrying the usual reed 10 1. At each side of and intermediate the ends of the frame 102 are rotatably mounted rollers 105, each of which engages with cams 106 secured adjacent to each end of the shaft 20 by set screw 107. The frame 102 is urged into its extreme left hand position, as shown in Fig. 1, by the spring 121 and, therefore, such spring acts to maintain the rolls 105 in engagement with the cams 106 at all times. Pivotally attached to the lower end of the lever 97 is the upper end of the connecting rods 108 and this connecting rod is pivotally attached at its lower end to the oscillating frame 102. The pairs of rolls 6771 and 86-90 are rotated simultaneously with the operation of the rectangular frame 102 and, therefore, simultaneously with the operation of the reed 10 1 uch reed moving from the full line positibii shown in Fig. 6 to the dotted line position shown therein.

Secured to the shuttle member 34 by screws 110 and forming part of the shuttle are outwardly extending arms 111. Formed integral with the arms 111 and lying parallel to the shuttle member 34 is a member 112, this member being provided with a horizontal slot 113. Formed integral with the shuttle member 341 and extending outwardly'therefrom are bracket members 11 1 drilled to receive the reduced end of thumb nuts 115. The

brackets 11% are spaced apart from each other, as clearly shown in Fig. 9, and threadcd into the thumb nuts 115 are the threaded ends of a shaft 116 and in such shaft is rotatably mounted abobbin 117'for carrying the flat tapelike material 118 forming the woof filamentof the fabric. Between the member 112 and the bobbin 117 and attached to the arms 111 is -a guide member 119, this member being also provided with a slot 120 through which passes the tapelike material 118. As the tapelike material 118 is pulled through the slot 113 in the member 112, such slot and also the guide 120 will maintain the same in a flat or horizontal position and with the glazed side of such material uppermost. The reciprocating motion of the shuttle member 34 carrying the bobbin 117 and with the material 118 passing through the slot 113 in the member 112 will lay such material 118 between the alternating warp threaded and with the glazed face uppermost;

After each passage of the material 118 be tween the alternating warp filaments the reed 104 is operated by the cams 106 and the reed frame 103 returned to its initial position, as shown in Fig. 1. This weaving operation is performed indefinitely and as long as ma- I claim as new is:

1. In a device of the kind described, the combination of a shuttle race, a shuttle, slotted means for delivering fiat tapelike material therefrom in predetermined position with relation to the shuttle, and aslOt-ted member interposed between said slotted means and said shuttle and adapted to guide said flatmaterial to said slotted delivery means in said predetermined position.

2. In a device of the kind described adapted for producing a basket-weave article, a shuttle body member, a bobbin rotatably mounted thereon and carrying a flat tapelike filament, a member provided with a slot lying in a horizontal plane and extending parallel to the body member, the slot acting to deliver the tapelilie filament from the bobbin in predetermined flat position, and a slotted guiding member interposed between said first slotted member and said bobbin.

3. In a power driven loom of the kind described adapted to produce a basket-weave from flat tapelike strips in both warp and woof, means to hold the warp in predetermined flat position, in combination with auto matic means to feed from a shuttle corresponding fiat woof tapelike strips in a similar flat predetermined position, whereby a resultant basket-weave is produced with all strips interwoven in the plane of their greatest width.

4. The improved process of producing an interwoven basket-weave material by a power actuated loom, which consists in providing the warp strips with means to hold the same in flat predetermined position, with the side of the greatest area to be exposed in the resultant material, providing similar fiat strips in a power'driven shuttle, with means to pre determine the feed of said strips from said shuttle to maintain the same similarly with the side of greatest width to be exposed in the resultant material, whereby a basketweave article is produced in a power driven loom.

In testimony whereof, I have si ned my name to this specification.
